Why will the cursor suddenly change to an hourglass?
Page 2 Stage reformats in the background as you edit. However, sometimes an action you take, such as Page Down, will take the part of the script shown in the window, past the correctly formatted portion of the script. When this happens, the cursor will change to an hourglass and you will not be able to do anything until that part of the script is formatted and the cursor returns to the standard I-beam shape.
